Blender 2.82 Parts of solid (opaque) objects in cycles renders are slightly transparent in photoshop
After having a look at your file (without textures attached) I have several suspicions:


"Noah's place bighter 2.exr" may have alpha issues
World background nodes> "Background" node itself was set to 0.920 instead of 1.
Compositor nodes> "Composite" node was set to "Use Alpha". Disable that?
Render settings>Film>Transparent>"Transparent Glass" was on. Turn off if you don't need it.
Render settings>Film>"Transparent" was on. Turn off if you don't it.


You can also check the alpha of your render directly in blender "render" window by right clicking the final render image and holding the mouse cursor over image pixels in question. It reads out RGB and alpha values.
